He might have written in a style that moved you, but it appears that much of what he wrote was untrue. I happen to like Peter Hathaway Capstick's books, but knowing that he inserted himself into other people's experiences has tempered my appreciation for his writing.
I have 3 Clay Harvey books in my library and they are OK reads, but certainly not in the upper class of writers like O'Connor, Keith, Wootters, or Koller. It seems to me that he rode the coat tails of his buddies Layne Simpson and Rick Jamison. Who knows, he might end up as a great fiction writer, he certainly has had enough practice. Since he and Layne were such good buddies, you might reach Clay via Layne.
